' IMPROVEMENT IN SEWING-MACHINE ATTACHMENTS.

Specification forming part of Leitrrs Patent No. 152,374. dated June 23,1874; application filed March 13, 1874.

To all whom it may concern Be it known that I, FRANK HENRY, of the cityand county of Philadelphia and the State of Pennsylvania, have inventeda new and useful Improvement in Sewing-Machine Attachments; and I dohereby declare the following to be aclear and exact description of thenature thereof, sufficient to enable others skilled in the art to whichmy invention appertains to fully understand, make, and use the same,reference being had to the accompanying drawings, makin g part of thisspecification, in which- Figure 1 is a plan or top view of the deviceembodying my invention. Figs. 2 and 3 are views of two opposite sidesthereof. Fig. 4 is an end view of a detached portion. Fig. 5 is a topview of a modification.

Similar letters of reference indicate like parts in the several figures.

It is well known that, owing to the difference in the construction ofsewing-machines, there is no uniformity of the location of the openingsin the cloth-plates for the reception of the screws which clamp variousattachments to the plates in juxtaposition to the needle-openings.

In attachments in use the joints between the bodies thereof, and gagesby which the attachments are clamped to the cloth-plate, have been soconstructed that, in order to adjust the attachments relatively toneedle-openings, the bodies and gages required to be set carefully at anacute or obtuse angle to each other, in order that the working portionof the bodies may stand at an exact right angle to the longitudinaldirection of the plate, whereby the work may not be irregularlyperformed.

My invention consists in the attachment, having a laterally-extendingplate, which is providedwith an eye and flat portion, in combinationwith a link or loop, which extends at right angles to the attachment,and is connected to the gage which bears against the flat portion of theplate of the attachment.

Referring to the drawings, A represents the clamping gage of a sewingmachine attachment, B. The working portion. or body 0 of the attachmenthas connected to, or formed with, one side thereof alaterally-projecting plate,-:D,= a portion of which is formed into agroove or eye, G, and the remaining portion G is horizontally flat, andextends in line parallel with the bottom of the said body. (See Fig. 4.)The inner portion of the gage, or portion which is to be connected tothe body 0, is formed with eyes H, through which passes one limb of aloop or linkshaped piece, J, another limb of which is inserted into theeye or groove G of theplate D, and when the parts are in position theportion of the gage A which is formed with the eyes H will rest on theportion G of the plate 1).'

It will be seen that, in order to adjust the attachment relatively tothe needle-hole in the longitudinal direction, the gage will beoperated. as usually, and when the proper position is obtained thetransverse adjustment of the body of the attachment is readily performedby simply sliding the said body, (the gage not having been tightened,)so that when the adjustmentis accomplished the right-angular connectionof the gage A and body 0 has been maintained. The pressure of the innerportion of the gage A. on the part D of the body 0 will firmly hold thelatter in place.

Having thus described my invention, what I claim as new, and desire tosecure by Letterslatent, is-

The laterally-extendillg plate 1), adapted to be secured to, or formingpart of, an attachment, and provided with eye G and flat portion G, incombination with the 'link or loop J, and the gage A resting on saidportion G, all substantially as and for the purpose set forth.

FRANK HENRY.
